Getting Started with the DFU

[c cook]

I'm using SDK 7.1, PCA10028 eval board, SD110, MCP 3.8.0.7

I've compiled and loaded the dfu_dual_bank_ble_s110 project into my PCA100028 board. It shows up in the MCP as :DfuTag. I connect and discover services. The DFU button in the MCP is active. So far so good.

I click the DFU button, and it is looking for a ZIP file, not a bin file - I can't find any zip files in the examples - How does one generate the ZIP files?

All the documentation I can find for using the DFU reference MCP Version 3.7 - which doesn't use ZIP files.

Is there a document/tutorial that walks through using the DFU with MCP version 3.8?

Thanks

It's in the docs here Creating a zip with image and init packet. I finally got DFU working but spent a couple of days pouring over docs, forum posts, and trying many things that didn't work.

A full walkthrough from zero with the latest tools and SDK would be welcomed by all I think.

I spoke too soon, I've managed to DFU after flashing bootloader but extending my app or even using the ble_app_hrs example to trigger reset to bootloader doesn't work for me.
